Does biofeedback therapy improve quality of life in children with lower urinary tract dysfunction: parents' perspective.

INTRODUCTION: Lower urinary tract dysfunction (LUTD) is a situation that often disrupts the quality of life (QoL) of both the child and the family with daytime and nighttime incontinence. Although the first-line treatment option for children with LUTD is standard urotherapy, biofeedback therapy can be performed in children in which standard urotherapy failed. OBJECTIVE: We studied the biofeedback success in children with LUTD according to parents' expressions. METHODS: We retrospectively analyzed our hospital records of children who were diagnosed with LUTD between 2005 and 2017. In total, 281 patients, refractory to standard urotherapy were included into the study and directed to biofeedback treatment. Their parents completed the dysfunctional voiding symptom scores (DVSS) before and after biofeedback therapy. RESULTS: At the end of the six-month follow-up period, all voiding disorders and voiding patterns were evaluated. According to DVSS, QoL tools before biofeedback treatment 48 (17%) parents appraised that LUTD caused no effect in their children's daily life, 104 (37.8%) expressed little effect, 89 (31%) moderate effect, and 40 (14.2%) serious effect. And, 120 (43%) parents expressed no effect, 95 (34%) little effect, 51 (18%) moderate effect, and 15 (5%) serious effect (P = 0.001) after biofeedback therapy. Biofeedback therapy affected positively the daily life of LUTD's family. The less serious the effect of LUTD on these children's family, the more success rate of biofeedback therapy. The effect of biofeedback therapy was less successful in moderated and serious affected families. CONCLUSIONS: Biofeedback treatment is a non-invasive and effective treatment modality for improving the QoL for LUTD families who were less suffered from LUTD.

Three Distraction Methods for Pain Reduction During Cystoscopy: A Randomized Controlled Trial Evaluating the Effects on Pain, Anxiety, and Satisfaction.

BACKGROUND: Cystoscopy is a safe diagnostic procedure commonly used to evaluate lower urinary tract symptoms. This can cause pain, anxiety, and dissatisfaction in patients undergoing cystoscopy. OBJECTIVES: The aim of this study was to compare the effects on pain, anxiety, and satisfaction of distraction methods used during cystoscopy. DESIGN: Single-center, open-label, randomized, parallel-group trial. SETTING: Cystoscopy unit of a training and research hospital in Turkey. PARTICIPANTS: Male patients ≥18 years of age who underwent rigid cystoscopy for the first time. METHODS: A total of 120 male patients were recruited and randomized into four groups as music, stress ball, video, and control group. Data were collected using visual analog scale for pain and satisfaction, State-Trait Anxiety Inventory for anxiety, and hemodynamic parameters. The primary outcome was the difference with respect to pain scores among intervention groups. Other outcome measures were anxiety and satisfaction scores. RESULTS: Pain severity during cystoscopy was found to be significantly lower in the intervention groups than the control group. In the video group, the severity of pain during cystoscopy was also found to be significantly lower than music and stress ball groups (p = 0.006, p < 0.001). After cystoscopy, anxiety levels were significantly lower and satisfaction levels were significantly higher in the intervention groups than in the control group. Anxiety levels were significantly lower in the video group than music and stress ball groups (p < 0.001, p < 0.001). Satisfaction levels were also significantly higher after cystoscopy in the video group than in the music and stress ball groups (p = 0.018, p = 0.018). CONCLUSIONS: According to this study, distraction methods used during rigid cystoscopy were found to have a reducing effect on pain, anxiety, and dissatisfaction. As the results of the study are evaluated, video should be recommended to be the first preferred distraction method during rigid cystoscopy.

Biofeedback as a first-line treatment for overactive bladder syndrome refractory to standard urotherapy in children.

INTRODUCTION: Overactive bladder syndrome (OAB) and dysfunctional voiding (DV) are subgroups of lower urinary tract dysfunction (LUTD). Standard urotherapy is the first-line treatment option of OAB in children. OBJECTIVES: The aim was to investigate the use of biofeedback as a first-line treatment option in OAB refractory to standard urotherapy, and determine the factors affecting efficacy. STUDY DESIGN: Between 2005 and 2015, we retrospectively analyzed a total of 136 hospital records of children with OAB who had not previously used any anticholinergics and were refractory to standard urotherapy. Patients with urgency and/or urge incontinence and/or making holding maneuvers to suppress urgency were defined as having OAB symptoms, and resolution of these complaints was defined as successful biofeedback therapy. RESULTS: Seventy-three of 136 OAB patients' urgency recovered by biofeedback therapy with the success rate of 53% (p < 0.001). Sixty-two of 101 patients with holding maneuvers (success rate 61%) (p < 0.001), 70 of 101 patients with urgency incontinence (success rate 69%) (p < 0.001), 76 of 114 patients with daytime incontinence (success rate 66%) (p = 0.023), 87 of 97 patients with enuresis (success rate 89%) (p = 0.009), and 27 of 39 patients with dysuria (success rate 69%) (p = 0.007) recovered from their symptoms significantly. The mean lower urinary tract symptom score (LUTSS) was 16.38 and 8.18 before and after biofeedback therapies, respectively (p < 0.001) (Table). Patients without holding maneuvers (p = 0.045), daytime incontinence (p = 0.030), and enuresis (p = 0.045) had better recovery compared to the opposites. DISCUSSION: Biofeedback can be thought of as the first-line treatment option when standard urotherapy fails in children with OAB.

The role of urinary nerve growth factor for the diagnosis and assessment of the biofeedback success in children with dysfunctional voiding.

INTRODUCTION: Dysfunctional voiding (DV) occurs in neurologically normal children who are not able to establish brain control on detrusor muscle contractions (DMCs). It is also reported to be the result of incorrect voiding habits during toilet training. Children contract pelvic floor muscles (PFMs) to suppress DMC and DV begins. Urinary nerve growth factor (uNGF) is necessary for the synthesis and regulation of neurotransmitters, development of dorsal root ganglia (sensory neurons), and development of sympathetic cells during embryonic and post-natal life. uNGF has also a role in the intracellular signal transduction in nerve cells towards the target organ. To our knowledge, no study has investigated the association between uNGF, biofeedback treatment and DV in children. OBJECTIVES: The aim was to examine the potential effect of uNGF in the assessment of the effectiveness of biofeedback success in children with lower urinary tract disorders. STUDY DESIGN: Fifty-two children with the suspicion of DV and 48 children from a primary school reporting no urinary complaints were enrolled in this study from October 2010 to April 2013 in the Urology Department. uNGF levels were compared. RESULTS: The mean uNGF/creatinine (Cr) level was 0.23 ± 0.26 in the control group and 0.96 ± 0.88 in the DV group (p < 0.001). The mean uNGF/Cr levels in the DV group at baseline and at the end of biofeedback therapy at 6 and 12 months were 0.90 ± 0.78, 0.26 ± 0.32, and 0.40 ± 0.50, respectively (p < 0.001) (Figure). DISCUSSION: To our knowledge this study is the first to show the correlations between uNGF levels and biofeedback therapy in children with DV. Tissue NGF in 12 patients with overactive bladder (OAB)/detrusor overactivity and 15 healthy women was previously compared and it was suggested that there was no correlation between bladder tissue NGF and OAB. uNGF levels in the bladder in patients with interstitial cystitis and idiopathic sensorial urgency were evaluated previously, and uNGF levels reported. Similar to these reports, most of the previous studies handled uNGF in patients with diseases such as interstitial cystitis, OAB, urinary tract infections, urolithiasis, spinal cord injury, and prostate cancer, and found significantly higher uNGF levels. These studies were generally in adults. A previous study about uNGF comprised 40 children with OAB, in contrast to other studies. According to this study, 40 children diagnosed with OAB were administered anti-muscarinic therapy (oxybutynin 0.3-0.5 mg/kg/day). It was reported that uNGF/Cr levels of the OAB group were higher than control group. In the current study, we evaluated the uNGF difference in DV and the effect of biofeedback treatment on uNGF levels. CONCLUSIONS: uNGF levels were higher in children with DV and decreased after biofeedback therapy. uNGF levels could be used for the diagnosis and the assessment of biofeedback success in these children.

The biofeedback treatment for non-monosymptomatic enuresis nocturna.

AIMS: Enuresis is a child older than 5 years wetting in discrete portions during sleep. It has two subgroups: monosymptomatic enuresis nocturna (MSEN) and non-monosymptomatic enuresis nocturna (NMSEN). In this research, we specifically aimed to examine the effect of biofeedback in NMSEN. METHODS: We retrospectively analyzed the hospital records of 182 children with NMSEN who were refractory to urotherapy modifications and directed to biofeedback therapies between 2005 and 2010. Enuresis before and after biofeedback therapies was evaluated. One or less enuretic night in a month was defined as success. RESULTS: There were 118 (64%) girls and 64 (35%) boys. With biofeedback therapy, 117 of 182 patients recovered with a success rate of 64% (P < 0.001), but 65 patients still had enuresis. Seventy-two out of 118 girls recovered with a success rate of 61% (P < 0.001), whereas 45 out of 64 boys recovered with a success rate of 70% (P = 0.001). The NMSEN complaints of daytime incontinence, dysuria, urgency, holding maneuvers, and urgency incontinence disappeared significantly concomitant to the enuresis component, as well (P < 0.05). CONCLUSIONS: Biofeedback therapy is an effective treatment option for the enuresis component of NMSEN with a 64% success rate.

Treatment of Priapism with Automated Red Cell Exchange and Hyperbaric Oxygen in an 11-year-old Patient with Sickle Cell Disease.

Priapism affects up to 50% of all males with sickle cell disease, and there is no standard treatment. Delayed and unsuccessful treatment leads to corporal fibrosis and impotence. It is therefore necessary to determine the best treatment methods for this complication in order to offer effective interventions to all affected patients. Herein we report an 11-year-old patient with sickle cell disease that presented with priapism 72 h after onset, and was successfully treated with automated red cell exchange and hyperbaric oxygen following unsuccessful surgical and conventional interventions.

Management of abnormal postvoid residual urine in children with dysfunctional voiding.

OBJECTIVES: To evaluate the effect of biofeedback therapy on the residual urine volume in children with dysfunctional voiding. METHODS: This prospective study was conducted in children with dysfunctional voiding associated with abnormal postvoid residual urine (PVR) from June 2002 to 2007. The children were divided randomly into 2 groups. Group 1 was treated with standard urotherapy combined with biofeedback therapy and group 2 was treated with only standard urotherapy. The outcomes of uroflow-electromyography pattern, urinary tract infection (UTI), and PVR were recorded before and at the end of sixth month of treatment. RESULTS: A total of 94 patients were enrolled in this study. Groups 1 and 2 consisted of 62 and 32 patients, respectively. The voiding pattern became normal in 80.6% (50/62) and 56.2% (18/32) of patients in groups 1 and 2, respectively. The PVR resolved in 40 of 62 (64.5%) patients in group 1 and in 11 of 32 (34.4%) children in group 2. Before the treatment, UTI was noted in 22.5% of patients (14/62) in group 1 and 21.8% of patients (7/32) in group 2. After the treatment, UTI was observed in 3.2% of patients (2/62) and in 9.3% (3/32) of patients in groups 1 and 2, respectively. Although both treatment modalities changed the voiding pattern, rate of febrile UTI, and PVR positively, these outcomes were better in a combination group. CONCLUSIONS: The combination of standard urotherapy with the biofeedback therapy improved the results significantly.

Effect of biofeedback treatment on spinning top urethra in children with voiding dysfunction.

OBJECTIVES: Spinning top urethra (STU) deformity arises secondary to detrusor instability, leading to an increase in the intravesical pressure against a closed sphincter. We retrospectively analyzed the effect of biofeedback treatment on STU in children with dysfunctional voiding. METHODS: A total of 121 patients with STU and voiding dysfunction were enrolled in this study. The patients divided into two groups. Group 1 (n = 49) were treated with simple bladder retraining with timed voiding, and group 2 (n = 72) were treated with biofeedback therapy. Voiding cystourethrography was performed 6 and 12 month later to determine the status of the STU after both therapies. RESULTS: The patient age range was 5 to 13 years (mean 8.1 +/- 1.9) in group 1 and 5 to 13 years (mean 8.2 +/- 1.7) in group 2. Group 1 consisted of 41 girls and 8 boys; group 2 consisted of 63 girls and 9 boys. Voiding cystourethrography revealed vesicoureteral reflux in 39 and 59 children in groups 1 and 2, respectively. The improvement rates of the biofeedback therapy in children with STU and vesicoureteral reflux were significantly greater than the children treated with timed voiding at 6 months and 1-year of follow-up. CONCLUSIONS: For children admitted to urology clinics with urinary infection or complaints thought to be an unstable urinary bladder, proximal urethral dilation called STU is detected at a high frequency. It should be remembered that this situation can be related to vesicoureteral reflux and urinary bladder instability. Biofeedback training is a simple, effective, and well-tolerated treatment modality for these children.

Results of biofeedback treatment on reflux resolution rates in children with dysfunctional voiding and vesicoureteral reflux.

OBJECTIVES: It is well known that a relationship exists between vesicoureteral reflux (VUR) and dysfunctional voiding, and the spontaneous resolution rate in older children is lower than the rate in younger children. In this study, we analyzed our experience with biofeedback treatment in older children with confirmed voiding dysfunction and VUR and investigated the effect of this treatment on the reflux resolution rates in these children. METHODS: A total of 78 children, 5 to 14 years old (mean age 9), with voiding dysfunction and VUR detected by voiding cystourethrography were treated with biofeedback therapy. Voiding cystourethrography was performed 6 months after completion of the biofeedback program to determine the reflux status. The treatment results were also documented as subjective and objective improvements. RESULTS: The reflux in 98 units (20 bilateral) was grade 1 in 26, grade 2 in 32, grade 3 in 28, and grade 4 in 12. At 6 months of follow-up, VUR had resolved on voiding cystourethrography in 62 units (63%), the grade had improved in 28 units (29%), and the reflux had remained unchanged in 8 units (8%). Among the older children treated with biofeedback, we also observed improvements in nocturnal enuresis (82%), daytime wetting (70%), constipation (78%), frequency (76%), infrequency (64%), urgency (71%), staccato voiding (81%), flattened voiding (81%), bladder overactivity (82%), detrusor sphincter dyssynergia (77%), spinning top urethra (67%), and urinary tract infection (80%). CONCLUSIONS: Biofeedback therapy is applicable in older children with dysfunctional voiding and VUR and yields greater resolution rates than the historical resolution rates.

The effect of biofeedback treatment on voiding and urodynamic parameters in children with voiding dysfunction.

PURPOSE: We studied the effects of biofeedback treatment on voiding and urodynamic parameters in children with voiding dysfunction. MATERIALS AND METHODS: We prospectively studied 188 children between June 1998 and November 2003. Biofeedback was performed with a urodynamics processor that enables simultaneous recording of urine flow and electromyography, and visual display of flow/electromyography activity. At the beginning of the study this treatment was performed once weekly. After patients understood the concept and performed homework regularly sessions were scheduled at 3 to 4-week intervals and continued for 6 months. All children were evaluated at 6 months and again at 2 years after completing biofeedback training. RESULTS: The number of the children completing biofeedback was 168 (89.4%). Improvement was obtained in all parameters, ranging from 59.2% to 87.8% at 6 months. Maximum improvement was acquired with flattened voiding in 65 of 74 children (87.8%), whereas the least improvement was acquired with daytime wetting in 58 of 98 children (59.2%). These improvements continued at 2-year followup, and ranged from 53.1% to 87.3%. While the rate of improvement for nocturnal enuresis, staccato voiding, detrusor-sphincter dyssynergia, vesicoureteral reflux and urinary tract infection had increased, the remaining parameters had decreased at 2-year followup. CONCLUSIONS: Biofeedback training is a simple, effective and well tolerated treatment modality in children for various parameters resulting from bladder dysfunction. Motivation and willingness to participate in biofeedback treatment are important selection criteria.
